This patch fixes the following warnings (with gcc 4.2.3)
defaults.c:980: warning: unused variable 'replace'
main.c:504: warning: 'watchPath' may be used uninitialized in this function
main.c:504: note: 'watchPath' was declared here
startup.c:616: warning: implicit declaration of function 'XrmUniqueQuark'
The handling of user defined shortcuts was not checking the length
of the shortcut before copying it to a fixed-length temporary buffer,
char buf[128];
strcpy(buf, shortcutDefinition);
and strcpy() is well known for not checking if overflows will occur.
In particular, wmaker was crashing here if a big 'shortcut' was defined
either through WPrefs or by directly editing the configuration files.
This is now avoided by using strncpy() instead.
And this patch also fixes a similar buffer overflow for big workspace
names too.
Furthermore, use MAX_SHORTCUT_LENGTH instead of raw number and define
it to be 32 instead of 128.
There may be issues with running applications in 64-bit mode when
they were written with tacit assumptions about 32-bit platforms.
For example,
* Assuming that a pointer can be cast back and forth to an integer
The reason is that the size of the integer and pointer may be different.
See the description of "[PATCH] Warn when casting a pointer (constant)
to an integer of different size." in the gcc mailing list
http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01881.html
where it was also suggested the use of casts to uintptr_t. This is
what this patch does.
As a result the following warnings are fixed, leaving us with an
almost warning-free compilation in 64-bit platforms:

This patch adds the --disable-verbose-compile switch to the
configure script.
When this option is used it reduces the verbosity of compilation
messages to the essential. However compiler warnings are not affected
and thus gain visibility by not standing in the middle of a storm
of other messages.
In summary, the compilation messages are reduced to a stream of
CC array.o
CC bagtree.o
CC configuration.o
CC connection.o
CC data.o
